Nokia IS-IS Routing Protocol Sample Questions (Q18-Q23):

NEW QUESTION # 18
A new router is added to a broadcast network. What does IS-IS use as the tiebreaker for selecting the DIS if the priorities are the same?

  • A. The Hello packet with the highest sequence number.
  • B. The router with the highest system ID.
  • C. The existing DIS remains the DIS.
  • D. The router with the highest interface MAC address.

Answer: B

Explanation:
In IS-IS, the Designated Intermediate System (DIS) is responsible for certain tasks on broadcast networks, such as generating link-state advertisements and acting as the central point for flooding information.


NEW QUESTION # 19
A routing domain is using a single-area link-state routing protocol. Which of the following is NOT information that a router can share with other routers in the domain using protocol-specific messages?

  • A. A copy of the local routing table.
  • B. The IP prefixes of subnets directly attached to the router.
  • C. The local router ID and the router IDs of neighboring routers.
  • D. IP prefixes known by the router because it is running ad additional routing protocol.

Answer: A

Explanation:
In a single-area link-state routing protocol (such as OSPF), routers share specific information about the network topology, not their entire routing table. They exchange link-state advertisements (LSAs) that contain information about their directly connected interfaces and their state, allowing other routers to build a consistent view of the network.


NEW QUESTION # 20
For a link-state routing protocol, which of the following statements about link-state updates is FALSE?

  • A. Aging helps ensure that routers that are no longer part of the topology will eventually get removed from the link-state database.
  • B. When a router detects that a link-state update has reached its maximum age, it will request a new update from the source router.
  • C. The age value is updated as the link-state update is flooded throughout the network and when it is in the link-state database
  • D. When a link-state update reaches its maximum age on a router, the router will flood that update to its neighbors.

Answer: D

Explanation:
When a link-state update reaches its maximum age, it is removed from the router's link-state database, not flooded to its neighbors. This prevents outdated information from continuing to affect the routing decisions. The router does not flood the aged update; instead, it will typically request a new link-state advertisement from the original source router if the information is still needed.


NEW QUESTION # 21
When multiple routing protocols offer a route for the same prefix, what part of the router is in charge of deciding which route to make active?

  • A. The equal cost multipath configuration
  • B. The forwarding information base (FIB)
  • C. The routing information base (RIB)
  • D. The routing table manager (RTM)

Answer: D

Explanation:
The routing table manager (RTM) is responsible for selecting the best route when multiple routing protocols provide a route for the same destination prefix. It makes the decision on which route to add to the routing table based on the administrative distance, metric, and other criteria.


NEW QUESTION # 22
Which of the following statements about router interfaces on a Nokia 7750 SR is FALSE?

  • A. The system interface exists by default.
  • B. They can be logical or physical.
  • C. They can be assigned IPv4 and/or IPv6 addresses.
  • D. They can be used in pairs on the same subnet for redundancy.

Answer: D

Explanation:
Typically, interfaces on a Nokia 7750 SR router are not configured in pairs on the same subnet for redundancy. Instead, redundancy is achieved through mechanisms like Virtual Router Redundancy Protocol (VRRP) or other high availability protocols, not by simply using interfaces in pairs on the same subnet.
